目的　探讨大肠癌根治术中脾脏损伤的防范及处理。方法　对大肠癌根治术中 9例病人损伤脾脏的原因及处理进行分析。结果　本组大肠癌术中脾脏损伤发生率为 0 81 %。主要原因有 :①为使近端结肠无张力吻合或处置时 ,在未游离脾结肠韧带或该韧带有粘连或挛缩时 ,强力牵拉结肠 ,致脾包膜撕脱 (6例 ) ;②麻醉不满意 ,或显露不满意时 ,为达到良好显露 ,用拉钩强力牵扯致脾脏挫伤 (2例 ) ;③粗暴探查致脾包膜撕裂 (1例 )。 9例均手术中发现 ,7例行脾修补 ,1例行脾切除 ,1例行脾部分切除 ,均治愈。结论　大肠癌根治术中所致脾脏损伤 ,均是为求良好显露或近端肠管无张力 ,而强力牵拉脾结肠韧带或切口所致 ,因而应针对上述原因积极预防 ,如有发生 ,应针对损伤情况 ,予以相应处理 Objective To investigate the prevention and treatment of spleen injury in radical operation of colorectal cancer. Methods The causes and treatment of spleen injury in 9 patients during radical operation of colorectal cancer were analyzed. Results The incidence of intraoperative spleen injury in colorectal cancer was 81.1%. The main reasons are: ① in order to make the proximal colon tension-free anastomosis or treatment, in the absence of free splenic ligament or the ligament adhesions or contractures, the strong pull the colon, splenic capsule avulsion (6 cases); ② anesthesia Dissatisfied, or revealed dissatisfaction, in order to achieve a good show, with a strong pull hook caused spleen contusion (2 cases); In all 9 cases, 7 cases were treated with splenectomy, 1 case with splenectomy and 1 case with splenectomy, all of them were cured. Conclusions The spleen injury caused by radical operation of colorectal cancer is for the sake of good exposure or tension-free proximal intestine, which is caused by strong traction of splenic colonic ligaments or incisions. Therefore, it should be actively prevented against the above reasons, and if so, Injury situation, be dealt with accordingly
